if the fuse is ok then use a power probe or multimeter to check the lights are getting some power to them and go from there the revs going up and down sounds like you may have a dogey idel controlo valve i would give it a clean then refit it if this dont work i would replace it they are not expensive ging hope this helps

The post above me is excellent advice and I agree I don't think the two problems are related.

Idle air control valve is easily checked by starting your car and pulling off the little rubber hose - the revs should climb immediataly (as if it's a cold winter's morning and your engine is starting from being cold).

If there's no power going through to your rear plate lights trace the wiring loom and find the earth, it could be corroded. Whether or not the number plate lights share their earth straps with your rear tail lights I don't know entirely.
